Holiday Travel: What 43 Million Americans Can Expect

Jupiterimages/Thinkstock(NEW YORK) — As 43 million Americans prepare to travel for Thanksgiving this week, some will have to brave snow, wind and heavy rain as they trek to their holiday destinations.

Bad weather will cause a rough start for some travelers expected to be on the move this week, 90 percent of whom will be travelling in cars. Snow is forecast for mountain passes in Washington state by Thanksgiving, and heavy flooding in Northern California is already creating dangerous road conditions in the West.

A closed vortex will drop over the Northeast Pacific and move slowly southward, bringing in the wet and soggy conditions to the region, according to the National Weather Service. In the areas with the highest terrain, temperatures are forecast to be low enough to support snow, creating rough conditions for motorists.

“Thirty-nine million people will be traveling in cars, so interstates and the roads are going to be very busy,” AAA spokesman Michael Green told ABC News.

In the air, very few delays are expected, as the airlines are looking forward to clear weather for the week.
